To all whom it may concern:

Be it known that 1, JAMES 'F'CoLLINs, a

citizen of the-United States,and aresid-ent of Marcusdn the county of Cherokee and State of Iowa, have invented a new and 1m roved My-invention has for its principal obj ectsto p elevator adapted to unload and elevate the contents of 'a-wagon means of a-team while attached "to the-wagon and to provide means for enabli-n-g thedevice to beused narrow passage- Ways and between cribs, so as to, convey grain to many different cribs or bins without removing the machine' or using a drag. Such objects haccomplish by the means illustrated in the accompanying drawings, in which drawings like characters of reference indi cate like partsthroug hout the views, and in' which Figure 1 is a side'elevation of .a combined dump ,andelevator embodying my invention. "Fig.2-is api-anv iew of thesame. Fig. 3 is .a side elevation of the parts shown in 'Fig. 1 with the horse tread and wagon-tread inclinedto the main frame of the machine. Fig. 41s a plan view of the machine, showing an elevator attached tothe rear end of the machine and extending -forwardly. Fig. 5 is an end view of the machine embodying my invention. Fig. 6 is an end view of a machine, showing the elevator extending at right angles to the main frame. Fig. 7 is a vertical longitudinal section taken on theline 7' 7 of Fig. 8, showing the clutch secured to the forward transverse shaft of a tread; and

Fig.8' is .a vertical transverse elevation taken on the line 8 8 of Fig. 7.

As illustrated in the drawings, 1 represents the main frame of the machine, which may be mounted upon runningear of any suitable Inclined a proaches may be extended from the ends 0 the mainframe to the ground-to enable a team and wagon to pass up onto the main frame and to descend therefrom. A tread 2 is mounted upon the forward end of themain frame and consists of an endless apron passing around end drums 3 and 4. The drum 3 is mounted upon a shaft 5,. journaled on the main frame. Side bars 6-are .also mounted upon the shaft 5 and form the sides of the frame upon which the tread 2 is mounted. The drum 4 is mounted upon a tranverse shaft 7, which is j ournaled in the forward ends of'the side bars by means of a pin 21*.

6 and extends at both ends beyond said side bars, so as :to rest on the side bars of the main frame,:andwhen in such osition sup orts the tread '2 in the'plane of the floor 0 the mainframe. The shaft 7 is adapted to be raised bodily with the'forward end of the tread 2, the rear end of the tread being held permanently in position by means of the transverse shaft 5, j ournaled in the sidebars of the main frame. The forward end. of the tread is elevatedby means of .a transverse shaft '8, journaled in bearin boxes *9, at-

wardly on the arc racks 12, and thereby ad just the inclination of thetread' 2 to develop the power required. The forward transverse shaft 7 is provided with a ciutch, consisting of an outer casing 13, freely mounted on'saidshaft and provided with a flanged hub 14. A collar 15 is :secured'to said shaft by means of set-screws 16 and holds the clutch in lace on said shaft.

A hea 1.7 is rigidly secured to the shaft 7 by means of a set-screw 18, and a spring band 19 is secured at one end to the side of said head by means of a stud or pivot 19*, and the opposite end "19 of said band is pivotally attached to one end of a link 20'by means of-a pivot-pin '20. The 0 posite end of said link is pivotally connecte tov a lever 21, that is fulcrumed on the clutch-head 17 The lever '21 isprovided with a weight 22 preferably in the form of a cylindrical disk, and the portion of the lever adjacent to said weight is connected to a .spring23, secured at its opposite end to the head 17 of the clutch by means ofv a in or stud 23. A brake-shoe isformed on t e end of a bar 24, which is rotatably mounted on a bracket 25, attached to the frame of the tread 2 and provided with a pulley 27, supporting a cord 26, one end of which cord is secured to the hub 14 of the outer casing of the clutch, and the opposite end 26 is secured to the main frame of the machine. The spring 23 holds the lever 21 normally in the position indicated in Fig. 8 of the drawings. As the speed of the tread increases the centrifugal force generated by the revolution of the IIO 7 around the hub 14 of the casing and shortens said cord, thereby pressing downward on the pulley 27, mountedupon the brakebar 24 and bringing the brake-shoe against the periphery of the head. 17, so as to retard the rotation of the shaft 7, upon which the said head is mounted. After the speed has been reduced by the brake-shoe the centrifugal force of the lever 21 is overcome by the spring 23 and the weighted end of the lever drawn inward by said spring toward the shaft 7, thereby drawing inward the free end 19 of the spring-band 19 and releasing said band from the inner wall of the casing 13, so as to enable said casing to ride idly on the shaft 7. A drive-shaft 28 is j ournaled in boxes 29, secured to the sides of the main frame, and the forward end of said shaft is provided with bevel-gears 30 and 31, adjustably'secured to said shaft by means of set-screws 30 and 31 as shown in Fig. 2, and adapted to engage a corresponding bevel-gear 32, secured to the end ofthe transverse shaft 5, upon which the rear end of the tread 2 is mounted. By means of the adjustability of the gears 30 and 31 on the shaft 28 either of said gears may be brought into engagement with the bevelgear 32, attached to the tread-shaft 5, and thereby rotate the shaft 28 to the right or left, asmay be desired. The rear end of the drive-shaft 28 is provided with a sprocketwheel 47 and with a worm 33. The worm 33 4 3 'which extends transversely of the rear end of engages a gear 34, attached to a shaft 35,

the main frame and is ournaled in suitable bearings on said frame. The shaft 35 is thereby adapted to rotate to the right or left as the bevel-gear 30 or 31 of the driveshaft 28 is brought into engagement with the gear 32 of the tread-shaft. A bevel-gear 36 is mounted upon the opposite end of the transverse shaft 35, and the extremities of said shaft are provided with sprocket-wheels 64 for the purposes hereinafter described.

A short shaft 38 is journaled on the end of the main frame and is provided on one end with a bevel-gear 37, adapted to engage the bevel-gear 36 of the transverse shaft 35. The opposite end of the shaft 38 is provided with a sprocket-wheel 39. The sprocket-wheel 39 of the short shaft 38 and the corresponding sprocket-wheel 47 of the drive-shaft 28 are adapted to operate a transverse conveyer secured to the end of the main frame and comprising an endless belt 44, mounted upon rums which are attached to shafts 42 and 45, having bearings in a transverse casing 43, secured to the end of 'the main frame, as shown in Fig. 3. The shaft 42 is provided with an outer spro cket-wheel and an inner sprocketwheel 66, and the opposite shaft 45 is provided with an outer sprocket-wheel 46 and an inner sprocket-wheel 46 as shown in Fig. 4. An endless belt 41 is connected with the sprocket-wheel 47, attached to the driveshaft 28, and with the sprocket-wheels 46, mounted in the shaft 46 of the transverse conveyer, so as to operate the transverse conveyer from the drive-shaft 28. The endless belt 41 may be removed from the sprocketwheels 46 and 47 and connected with the sprocket-wheels 39 and 40 on the opposite side of the main frame, so as to operate the transverse conveyer in an opposite direction.

An 0 ening is made in the rear end of the floor 0 the main frame of the machine directly above the transverse conveyer 44, and when the machine is not in use the opening is closed by a trap-door 48, secured to the rear end of the main frame by means of hinges 48 longitudinalbars, are pivotally mountedupon a transverse shaft 50, which is connected at its ends to the sides of the main frame. The forward ends of said treads are provided with are racks 51, which engage pinions 52, mounted upon a transverse shaft 53, journaled on the side bars of the main frame. The shaft 53 is provided with a ratchet-wheel 54, the teeth of which engage a pawl 55, secured to the main frame. The ends of the shaft 53 are preferably square, as shown in Fig. 2, and thereby adapted to be grasped by a wrench or crank, so as to rotate the shaft 53 and elevate or depress the forward end of the wagon-treads-49, as may be desired. An elevator is detachably mounted upon the end of the main frame by means of brackets 56, provided'with offset upper ends 56*, adapted to engage apertures 58, formed on the rear end of the main frame and on both sides thereof, so as to enable said bracket and the elevator supported thereon to be attached to either side of the mainframe; The bracket is provided on its lower. end with horizontal bars 57, adapted'to support a receiver 60, having an elevator-chute 59, pivotally attached thereto. The receiver is secured against displacement on the bracket by means of hooks 61, which engage the lower bars 57 of the bracket.

By means of such construction the elevator-chute 59 is adapted to extend backward from the machine, as shown in Figs. 1 and 2, or forward, as shown in Figs. 3 and 4, or at a right angle thereto, as shown in Fig. 6. The receiver 60 of the elevator is provided with a shaft 62, having sprocket-wheels 63 and 63 attached thereto on opposite sides of the receiver.

A standard 67 is secured to the rear end of the main frame in any suitable manner, preferably'by engaging apertures 58*, formed Wagon-treads 49, consisting of ITO on opposite sides of the end of the main 'adapt'edto berotated on its axisso-that the bent upper portion thereof may extend :to,

ward the rear, the front, or the side of the machine and support the elevator-chute 5'9 when arranged in either of such positions. An endless conveyer may be mounted on the elevator-chute 59 and receiver -f60-and connected with the shaft 62, having asprocketwheel 63 and 63 mounted thereon. The shaft 62 of the elevator is operated by means of the transverse shaft 35, when the elevator extends to the front or rear of the machine, an endless belt 65 connecting the end sprocket- Wheel 64 of the transverse shaft 35 with the sprocket-wheels mounted upon the transverse shaft 62 of the elevator. When, however, the elevator is extended outward at a right angle to the machine, the shaft 62 of the elevator is rotated by one of the end shafts of the transverse conveyer 44, the sprocket-wheels of which may be connected with the sprocket-wheels of'the shaft 62 by means of the endless belt 65, as shown in Fig. 6. An endless conveyer may be mounted upon the receiver 60 and chute 59 in any suitable manner, and connected with the shaft '62 so as to be operated thereby.

In the construction herein shown and described, I have provided a combined dump and elevator adapted to be operated Without detaching the team from the wagon being unloaded and have provided means for transferring the contents of the wagon to either side of the machine and for elevating such contents from'either side of the maebine in a direction forward or backward or directly outward therefrom, and I do not desire to be limited to the specific means herein shown and described for accomplishing such results, as other means having similar capabilities may be used without departing from my invention. 1
